Answer:

  x = 6

Step-by-step explanation:

You can actually work out the answer yourself.

The two angles shown have the total measure 168°, so the unmarked one is ...

  168° -100° = 68°

That is ∠WXZ, so we know ...

  68° = (5x +38)°

  30 = 5x . . . . . . . . . . divide by °, subtract 38

  6 = x . . . . . . . . . . . . .divide by 5

Determine the simple interest when:
ivann1987 [24]

Answer:

$75.65

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4.25%/100 = 0.0425 per year,

then, solving our equation

I = 890 × 0.0425 × 2 = 75.65

I = $ 75.65

The simple interest accumulated

on a principal of $ 890.00

at a rate of 4.25% per year

for 2 years is $ 75.65.
